Yes
Note
Have all condensate components included with the boiler been installed?
Is the condensate line piped with the approved materials listed in this manual?
Has the condensate line been routed to a laundry tub or other drain?
Install Gas Piping
Yes
Note
If operating on Propane, has the appropriate LP Conversion Kit been installed and the LP Conversion
Instructions been followed?
Is the gas supply line a minimum of 3/4” in diameter?
Is the gas supply line length and diameter adequate to deliver the required BTUs?
When operating at maximum and minimum gas input rates, does the gas line pressure remain between
3.5 and 14” WC for Natural Gas, or between 8 and 13” WC for Propane?
Does the gas type match the type indicated on the boiler rating plate? If converted to Propane, has the LP
Conversion Label been affixed adjacent to the boiler’s rating plate label?
Has a union and shut-off valve been installed?
Relief Valve
Yes
Note
Is the CH Pressure Relief Valve rated to 30 psi properly installed and the at least 3/4” discharge line run to
an open drain and protected from freezing?
Is the DHW Pressure Relief Valve rated to 150 psi properly installed and the at least 3/4” discharge line run
to an open drain and protected from freezing?
